The Islamic State in Iraq and Syria released a video on Saturday that showed the beheading of a British citizen, David Cawthorne Haines, an aid worker.Mr. Haines is seen kneeling on a bare hill in a landscape that appears identical to the one where two American journalists --James Foley and Steven J. Sotloff — were killed by the group in back-to-back-executions in the past month, according to the footage and a transcript released by SITE Intelligence, which tracks the terrorist group.

In the moments before his death, Mr. Haines, 44, as the two other journalists did before him, reads a script in which he blames his country’s leaders for his killing.

Addressing Prime Minister David Cameron of Britain, he says: “I would like to declare that I hold you, David Cameron, entirely responsible for my execution. You entered voluntarily into a coalition with the United States against the Islamic State.” He added: “Unfortunately, it is we the British public that in the end will pay the price for our Parliament’s selfish decisions.”
